I believe when the reaction is not under standard conditions. Bc the -0.0592 is calculated by plugging in standard temp and stuff into the equation.

^^ When under nonstandard conditions, I think you have to use the pressure and temp specified in the problem

^^ That number is derived from the assumption that the conditions for the experiment/ cell are normal, so you can't use -.0592 when the conditions of the problems aren't normal.

When the reaction doesn't occur under standard conditions.

What would the standard conditions be? Would it just be 1 mol at 298 K?

since this equation comes from inserting the temp at 298K, we shouldn't use this when the rxn is not occurring at standard conditions

Standard conditions are 1 mol/1 atm and temperature of 25 degrees Celcius, which is 298 K.

I think you are really asking when do we have to use something other than -0.0592. This would be whenever the temperature is not at 298.15K.

You cannot use that value when the reaction isn't under standard conditions.
